Choosing the right Heating and Air Conditioning Contractor is very important. Chances are you are going to make a substantial investment in your new HVAC system with which ever contractor you choose. There is nothing worse than investing a large amount of your hard earned money in a new system and winding up with a system that is noisy, inefficient, and does not perform properly. Or even worse, one that fails prematurely. Surprisingly enough most HVAC Contractors have no formal training. Untrained HVAC Contractors frequently do not size systems properly which could result in improper cooling, very high utility bills, and even systems that fail prematurely. Before you even consider a contractor make sure they are NATE Certified and Air Balance Certified. North American Technician Excellence is the Prestigious Certification of HVAC Competence. Using a NATE certified contractor is like using a surgeon that graduated Harvard Medical School with honors. Air Balance Certified contractors understand airflow which equates to efficiency and comfort in your home. To have a system designed properly a contractor has to understand air flow. At Southland we offer this high level of expertise. Yes, we are very good at what we do and there is no question about that. Our reviews and ratings prove that. Our installations are unparalleled with every system being designed specifically to the home. All options for a quality installation are included in every system we install. From basic systems, high efficiency systems, to specialized zoning we do it all. If you are searching for a knowledgeable contractor you have found one here. We offer extremely competitive pricing and expert design knowledge.

"Very well. They did the job quickly, quietly and cleanly."

Heating Oil questions, answered by experts

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Costs depend on system age, type, labor, and whether part replacements are necessary.
